fig. 2 is a schematic side view of the ground wire stand of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following drawings and detailed description:
referring to fig. 1 and 2, the ground wire frame of the present invention includes a pull rod 1, a central shaft 2, a winding frame 3, a turntable 4 and a spring 5.
The pull rod 1 comprises two symmetrically arranged telescopic rods 11 with adjustable height, and a transverse handheld rod 12 is connected between the tops of the two telescopic rods 11. The telescopic rod 11 comprises a fixed rod and a movable rod, the movable rod can be inserted into the fixed rod in a vertically movable mode, and the movable rod and the fixed rod are fixedly locked through jackscrews; the telescopic rod 11 may also be a draw-bar structure in a draw-bar box, which includes a plurality of sequentially inserted rods, and a positioning mechanism or a friction force between each two adjacent rods for locking by using an elastic member and a clamping groove.
Two rollers 13 are rotatably mounted at the bottom of the drawbar 1 for transportation.
Two brackets 14 are correspondingly arranged on one side of the pull rod 1 up and down, the two brackets 14 are welded on the fixed part of the pull rod, a central shaft 2 is rotatably arranged between the two brackets 14 through a bearing, and the central shaft 2 is vertically arranged.
Bobbin 3 includes that the equipartition sets up around the center pin and four wire winding poles 31 of vertical setting, and four wire winding poles 31 all are connected with center pin 2 through a plurality of horizontal poles 32, and bobbin 3 rotates along with center pin 2. The upper end and the lower end of each winding rod 31 extend outwards respectively to form a limiting plate 33, and the limiting plates 33 play a limiting role to avoid the wire from sliding out of the winding rods 31, so that the winding of the ground wire on the winding frame 3 is facilitated.
The lower end of the central shaft 2 is rotatably and coaxially connected with a rotary table 4 through a bearing, and the rotary table 4 and the rotary table are in transmission connection through a clockwork spring 5, namely one end of the clockwork spring 5 is fixedly connected with the outer wall of the lower end of the central shaft 2, and the other end of the clockwork spring is connected with the inner wall of the rotary table. Wherein the clockwork spring 5 is arranged in the rotary disk 4, and the lower end of the rotary disk 4 is fixedly connected with a rotation stopping rod 41 used for contacting the ground.
During operation, the ground wire clamp can be fixed on the cross rod 32 inside the winding frame 3, the external space cannot be occupied, the human body cannot be damaged, the pull rod 1 can be contracted at the back of the ground wire frame, the whole height is unchanged, the winding frame 3 is fixed on the central shaft 2, and the winding frame 3 can be wound with a group of ground wires. When the ground wire is stored, the winding frame 3 is fixed by hand, the rotating disc 4 is rotated to wind the spring, then the rotation stopping rod 41 touches the ground to fix the rotating disc 4, one end of the ground wire is fixed on the winding frame 3, and the central shaft 2 and the winding frame 3 can be driven to rotate through the action of the spring 5 so as to wind the ground wire on the winding frame 3.
The utility model discloses a ground wire frame has effectively improved the problem that hard, waste time in the work before, utilizes clockwork spring wire winding and the box transport of pull rod, has effectively improved the life of ground wire and has improved the phenomenon of transport difficulty, lets the later work of fortune dimension personnel high-efficient convenient more.
In summary, the present invention is not limited to the above embodiments, and those skilled in the art can provide other embodiments within the technical teaching of the present invention, but these embodiments are included in the scope of the present invention.
